CORK-CUTTING MACHINE.

Application filed March as,

To all whom it may concern.

Be it known that l, BERTHOLD Lanna, a citizen of the Republic of France,residing in Paris, France, have invented certain new and usefulImprovements in Cork-Cutting Machines, of which the following is aspecification.

This invention relates to an apparatus intended for cutting up strips orbands of cork into squares to be subsequently converted into corkstoppers.

The primary object of the invention is to provide an improvedarrangement of the cutting knife, cork band is produced.

A further object of the invention is to fur nish improved means by whichthe knife or cutter is ground and kept sharp, this means operatingduring the shearing movement of the knife and being actuatedautomatically by simple mechanism.

The invention also aims to provide improved mechanism for feeding thecork band to the knife.

in the accompanying drawing, Figure 1 is a front-elevation of a machineconstructed according to the invention, Fig. 2 is a side elevation ofthe same, Fig. 3 is a top plan view-v, and Fig. 4 is a detail elevationof part of the feed mechanism.

The machine embodies in its construction a horizontal slide 7: having atits upper and lower edges beveled portions Z, m about which fits acarriage 05 adapted to be reciprocated horizontally on said slide. Thisreciprocating movement of the carriage is produced by its connection atf with a connecting rod a secured at g to a wheel h driven by a pulley ior other suitable transmission.

Slidable vertically on the carriage (Z, by means of slides c, c, is asecond carriage 0 located at the front of the horizontally movingcarriage d. At the lower part of the carriage c the same carries a plateI) by means of which a knife or cutter a at the lower extreniity of thecarriage c is clamped in position. Said knife at the limit of itsdownward movement cooperates with a table T upon which the cork band tobe out is positioned.

The downward movement of the carriage c is produced by its connection byconnecting rods n, 0 with fixed pivotal supports p, (1 located above theslide 7:, as shown. (Ewing to this arrangement, when the carriage cl isreciprocated horizontally, the knife-carriage 0 will partakeiof itsreciprocatory movement Specification of Letters Patent.

Y and at the same time will be swung about the pivots p, g. Thismovement of the knifecarriage is indicated on Fig. 1 by the arrows l, 2,and it will be seen that the knife during its downward movement will bemoved laterally, while having its edge parallel to the plane of thetable, so as to give a shearing out to the cork band.

The cork band, which is denoted by reference character 1", is positionedon the table T by means of guides s, t, which are adjustably fixedagainst the side-edges of the band, as shown in Fig. 1. The feed of thecork band to the knife is effected by means of two feed-rolls a, o, ofwhich the upper feedroll a is mounted above the table to contact withthe upper surface of the band, while the lower feed-roll '0, which ispreferably fluted, contacts with the band at its lower surface. Theupper roll is acted on by means of springs r to press the band againstthe lower roll 1), and said upper roll a may be raised by pressing downon a lever 3 which pulls the roll a upwardly by means of a frame a onwhich the springs .r are placed. The lower roll o is actuatedintermittently from a ratchet-wheel 2 by means of gearwheels 19 and 20.The spindle of said roll carries a pulley 21 connected by means of anelastic belt with another pulley 22 carried by the upper roll, so thatthe latter is also given a movement of rotation. The ratchetwheel 2 isoperated by means of a pawl 1 secured to an arm 2 operated by aconnecting rod 3 adjustably secured to a disk 4. The disk 4 is providedwith a groove 5 in which the end of the connecting rod 3 is adjustablysecured, and consequently in this way the movement of the pawl andratchet can be controlled in order to give a feeding movement of theproper length. The disk 1 is mounted on a spindle 6, as shown in Fig. 3,this spindle receiving its movement from gear-wheels 7, 8, 9 and 10, ofwhich thelatter is keyed to the shaft of pulley i.

lhe mechanism for grinding the knife during its movement comprises anupright guide 17 supported by the table, and having vertically movabletherein a slide-piece 16 carrying spring-pressed grinding rollers 11,12, of which one presses against the rear face of the knife, while theother operates on its front-face, as shown best in Fig. 2. At its upperpart the slide-piece 16 carries rollers 14, 15 spaced apart from eachother and arranged at the upper and lower surfaces respectively of ahorizontal flange 18 extending across the knife-carriage c at its lowerportion. It is evident that during the movement of the carriage c in thedirection of the arrows 1, 2 the slide-piece with its rollers 11,

thereby effecting the sharpening of the same.

Having thus described my invention, I claim as new and desire Patent:

1. In a cork-cutting machine, the combination of a laterally movingcarriage, a knife-carriage slidable with respect to the first carriage,and means pivotally supporting said knife-carriage to cause a verticalmovement thereof.

2. In a cork-cutting machine, the combination of a laterallyreciprocating carriage, a vertically sliding knife-carriage thereon, anda fixed pivotal support for the knife- Qarriage located above the same.

3. The combination of .a laterally reciprocating carriage, aknife-carriage vertically slidable thereon, a fixed pivot, and aconnecting rod connecting the pivot with said knife-carriage to cause avertical movement of the knife during its lateral movement.

4. The combination of a laterally reciproeating carriage, aknife-carriage s'lidable vertically thereon, fixed pivots 'p, 1 abovethe knife-carriage, and connecting rods 11,0 connecting said pivots withsaid carriage.

5. The combination of a table, a carriage movable horizontally abovesaid table,

to secure by Letters means to reciprocate said carriage horizon-- tally,a knife-carriage slidable vertically on said first named carriage, aknife at the lower part of said knife-carriage, and a swingingconnection secured to said knife-carriage by which it is movedvertically.

'6. The combination of a knife-carriage carrying a knife, means to givethe same a r shearing i iovement, a slide-piece connected with saidcarriage and carrying grinding rollers, and means by wl ich the knife isdrawn between said rollers.

7. The combination of a knife-carriage having a combined lateral andvertical movement, a knife, and a slide having a vertical movement andcarrying grinding rollers .between which the knife is drawn.

8. The combination of a knife-carriage having a combined lateral andvertical movement, a knife on said carriage at the lower part thereof, aslide-piece having a vertical movement only, means connecting saidslide-piece with said knifecarriage by which the two move togethervertically, and grinding devices carried by said slide-piece betweenwhich :the knife is drawn laterally.

9. The combination of a carriage having a combined lateral and verticalmovement, a knife at the lower part of said carriage, a flange on thecarriage, a vertically moving slide-piece carrying rollers traveling onsaid flange at opposite sides, and grinding means on said slide-piecewith respect to which the knife is moved laterally.

In testimony whereof I have signed this specification in the presence oftwo subscribin g witnesses.
